Paul Davidson – Keynes’s Forgotten Lessons

Davidson discusses Keynes’s oft-forgotten insights into the foundational assumptions of economics. Classical economists were treated as “Euclidians in a non-Euclidian world,” Davidson says. “When they saw parallel lines intersecting they rebuked them for intersecting.” Keynes saw that the problem with Euclidean economics was what he called uncertainty, meaning the idea that the future cannot be predicted from the past — an insight that modern economics too often ignores.
